perf flamegraph: Use /bin/bash for report and record scripts (2020-05-05 16:35:32 -0300)
----------------------------------------------------------------
perf/core improvements and fixes:
perf record:
- Introduce --switch-output-event to use arbitrary events to be setup
and read from a side band thread and, when they take place a signal
be sent to the main 'perf record' thread, reusing the --switch-output
code to take perf.data snapshots from the --overwrite ring buffer, e.g.:
# perf record --overwrite -e sched:* \
--switch-output-event syscalls:*connect* \
workload
will take perf.data.YYYYMMDDHHMMSS snapshots up to around the
connect syscalls.
Stephane Eranian:
- Add --num-synthesize-threads option to control degree of parallelism of the
synthesize_mmap() code which is scanning /proc/PID/task/PID/maps and can be
time consuming. This mimics pre-existing behaviour in 'perf top'.
Intel PT:
Adrian Hunter:
- Add support for synthesizing branch stacks for regular events (cycles,
instructions, etc) from Intel PT data.
perf bench:
Ian Rogers:
- Add a multi-threaded synthesize benchmark.
- Add kallsyms parsing benchmark.
Tommi Rantala:
- Fix div-by-zero if runtime is zero.
perf synthetic events:
- Remove use of sscanf from /proc reading when parsing pre-existing
threads to generate synthetic PERF_RECORD_{FORK,MMAP,COMM,etc} events.
tools api:
- Add a lightweight buffered reading API.
libsymbols:
- Parse kallsyms using new lightweight buffered reading io API.
perf parse-events:
- Fix memory leaks found on parse_events.
perf mem2node:
- Avoid double free related to realloc().
perf stat:
Jin Yao:
- Zero all the 'ena' and 'run' array slot stats for interval mode.
- Improve runtime stat for interval mode
Kajol Jain:
- Enable Hz/hz printing for --metric-only option
- Enhance JSON/metric infrastructure to handle "?".
perf tests:
Kajol Jain:
- Added test for runtime param in metric expression.
Tommi Rantala:
- Fix data path in the session topology test.
perf vendor events power9:
Kajol Jain:
- Add hv_24x7 socket/chip level metric events
Coresight:
Leo Yan:
- Move definition of 'traceid_list' global variable from header file.
Mike Leach:
- Update to build with latest opencsd version.
perf pmu:
Shaokun Zhang:
- Fix function name in comment, its get_cpuid_str(), not get_cpustr()
Stephane Eranian:
- Add perf_pmu__find_by_type() helper
perf script:
Stephane Eranian:
- Remove extraneous newline in perf_sample__fprintf_regs().
Ian Rogers:
- Avoid NULL dereference on symbol.
tools feature:
Stephane Eranian:
- Add support for detecting libpfm4.
perf symbol:
Thomas Richter:
- Fix kernel symbol address display in TUI verbose mode.
perf cgroup:
Tommi Rantala:
- Avoid needless closing of unopened fd
libperf:
He Zhe:
- Add NULL pointer check for cpu_map iteration and NULL
assignment for all_cpus.
Ian Rogers:
- Fix a refcount leak in evlist method.
Arnaldo Carvalho de Melo:
- Rename the code in tools/perf/util, i.e. perf tooling specific, that
operates on 'struct evsel' to evsel__, leaving the perf_evsel__
namespace for the routines in tools/lib/perf/ that operate on
'struct perf_evsel__'.
tools/perf specific libraries:
Konstantin Khlebnikov:
- Fix reading new topology attribute "core_cpus"
- Simplify checking if SMT is active.
perf flamegraph:
Arnaldo Carvalho de Melo:
- Use /bin/bash for report and record scripts, just like all other
such scripts, fixing a package dependency bug in a Linaro
OpenEmbedded build checker.
perf evlist:
Jagadeesh Pagadala:
- Remove duplicate headers.
Miscelaneous:
Zou Wei:
- Remove unneeded semicolon in libtraceevent, 'perf c2c' and others.
- Fix warning assignment of 0/1 to bool variable in 'perf report'

Test results:
The first ones are container based builds of tools/perf with and without libelf
support. Where clang is available, it is also used to build perf with/without
libelf, and building with LIBCLANGLLVM=1 (built-in clang) with gcc and clang
when clang and its devel libraries are installed.
The objtool and samples/bpf/ builds are disabled now that I'm switching from
using the sources in a local volume to fetching them from a http server to
build it inside the container, to make it easier to build in a container cluster.
Those will come back later.
Several are cross builds, the ones with -x-ARCH and the android one, and those
may not have all the features built, due to lack of multi-arch devel packages,
available and being used so far on just a few, like
debian:experimental-x-{arm64,mipsel}.
The 'perf test' one will perform a variety of tests exercising
tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf commands
with a variety of command line event specifications to then intercept the
sys_perf_event syscall to check that the perf_event_attr fields are set up as
expected, among a variety of other unit tests.
Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/
with a variety of feature sets, exercising the build with an incomplete set of
features as well as with a complete one. It is planned to have it run on each
of the containers mentioned above, using some container orchestration
infrastructure. Get in contact if interested in helping having this in place.
Ubuntu 19.10 and debian experimental are failing when linking against
libllvm, which isn't the default, needs to be investigated, haven't
tested with CC=gcc, but should be the same problem:

But it's not calculated by the counts generated in this interval. See the following examples: root@kbl-ppc:~# perf stat -M CPI -I1000 --interval-count 2 # time counts unit events 1.000422803 764,809 inst_retired.any # 2.9 CPI 1.000422803 2,234,932 cycles 2.001464585 1,960,061 inst_retired.any # 1.6 CPI 2.001464585 4,022,591 cycles The second CPI should not be 1.6 (4,022,591/1,960,061 is 2.1) root@kbl-ppc:~# perf stat -e cycles,instructions -I1000 --interval-count 2 # time counts unit events 1.000429493 2,869,311 cycles 1.000429493 816,875 instructions # 0.28 insn per cycle 2.001516426 9,260,973 cycles 2.001516426 5,250,634 instructions # 0.87 insn per cycle The second 'insn per cycle' should not be 0.87 (5,250,634/9,260,973 is 0.57). The current code uses a global variable 'rt_stat' for tracking and updating the std dev of runtime stat. Unlike the counts, 'rt_stat' is not reset for interval. While the counts are reset for interval. perf_stat_process_counter() { if (config->interval) init_stats(ps->res_stats); } So for interval mode, the 'rt_stat' variable should be reset too. This patch resets 'rt_stat' before read_counters(), so the runtime stat is only calculated by the counts generated in this interval. With this patch: root@kbl-ppc:~# perf stat -M CPI -I1000 --interval-count 2 # time counts unit events 1.000420924 2,408,818 inst_retired.any # 2.1 CPI 1.000420924 5,010,111 cycles 2.001448579 2,798,407 inst_retired.any # 1.6 CPI 2.001448579 4,599,861 cycles root@kbl-ppc:~# perf stat -e cycles,instructions -I1000 --interval-count 2 # time counts unit events 1.000428555 2,769,714 cycles 1.000428555 774,462 instructions # 0.28 insn per cycle 2.001471562 3,595,904 cycles 2.001471562 1,243,703 instructions # 0.35 insn per cycle Now the second 'insn per cycle' and CPI are calculated by the counts generated in this interval.

Mimic perf top way of handling the option. If not specified will default to 1 thread, i.e. default behavior before this option. On a desktop computer the processing of /proc/PID/task/PID/maps isn't slow enough to warrant parallel processing and the thread creation has some cost - hence the default of 1. On a loaded server with >100 cores it is possible to see synthesis times in the order of seconds and in this case having the option is desirable. As the processing is a synchronization point, it is legitimate to worry if Amdahl's law will apply to this patch. Profiling with this patch in place: https://lore.kernel.org/lkml/20200415054050.31645-4-irogers@google.com/ shows: ... - 32.59% __perf_event__synthesize_threads - 32.54% __event__synthesize_thread + 22.13% perf_event__synthesize_mmap_events + 6.68% perf_event__get_comm_ids.constprop.0 + 1.49% process_synthesized_event + 1.29% __GI___readdir64 + 0.60% __opendir ... That is the processing is 1.49% of execution time and there is plenty to make parallel. This is shown in the benchmark in this patch: https://lore.kernel.org/lkml/20200415054050.31645-2-irogers@google.com/ Computing performance of multi threaded perf event synthesis by synthesizing events on CPU 0: Number of synthesis threads: 1 Average synthesis took: 127729.000 usec (+- 3372.880 usec) Average num. events: 21548.600 (+- 0.306) Average time per event 5.927 usec Number of synthesis threads: 2 Average synthesis took: 88863.500 usec (+- 385.168 usec) Average num. events: 21552.800 (+- 0.327) Average time per event 4.123 usec Number of synthesis threads: 3 Average synthesis took: 83257.400 usec (+- 348.617 usec) Average num. events: 21553.200 (+- 0.327) Average time per event 3.863 usec Number of synthesis threads: 4 Average synthesis took: 75093.000 usec (+- 422.978 usec) Average num. events: 21554.200 (+- 0.200) Average time per event 3.484 usec Number of synthesis threads: 5 Average synthesis took: 64896.600 usec (+- 353.348 usec) Average num. events: 21558.000 (+- 0.000) Average time per event 3.010 usec Number of synthesis threads: 6 Average synthesis took: 59210.200 usec (+- 342.890 usec) Average num. events: 21560.000 (+- 0.000) Average time per event 2.746 usec Number of synthesis threads: 7 Average synthesis took: 54093.900 usec (+- 306.247 usec) Average num. events: 21562.000 (+- 0.000) Average time per event 2.509 usec Number of synthesis threads: 8 Average synthesis took: 48938.700 usec (+- 341.732 usec) Average num. events: 21564.000 (+- 0.000) Average time per event 2.269 usec Where average time per synthesized event goes from 5.927 usec with 1 thread to 2.269 usec with 8. This isn't a linear speed up as not all of synthesize code has been made parallel. If the synthesis time was about 10 seconds then using 8 threads may bring this down to less than 4.

Replace the scanf call with manual reading of each field of the /proc/pid/maps line, and remove some unnecessary buffering. This change also addresses potential, but unlikely, buffer overruns for the string values read by scanf.

The "?" can be use for parameters whose value not known while creating metric events and which can be replace later at runtime to the proper value. It also add flexibility to create multiple events out of single metric event added in JSON file. Patch adds function 'arch_get_runtimeparam' which is a arch specific function, returns the count of metric events need to be created. By default it return 1. This infrastructure needed for hv_24x7 socket/chip level events. "hv_24x7" chip level events needs specific chip-id to which the data is requested. Function 'arch_get_runtimeparam' implemented in header.c which extract number of sockets from sysfs file "sockets" under "/sys/devices/hv_24x7/interface/". With this patch basically we are trying to create as many metric events as define by runtime_param. For that one loop is added in function 'metricgroup__add_metric', which create multiple events at run time depend on return value of 'arch_get_runtimeparam' and merge that event in 'group_list'. To achieve that we are actually passing this parameter value as part of `expr__find_other` function and changing "?" present in metric expression with this value. As in our JSON file, there gonna be single metric event, and out of which we are creating multiple events. To understand which data count belongs to which parameter value, we also printing param value in generic_metric function. For example, command:# ./perf stat -M PowerBUS_Frequency -C 0 -I 1000 1.000101867 9,356,933 hv_24x7/pm_pb_cyc,chip=0/ # 2.3 GHz PowerBUS_Frequency_0 1.000101867 9,366,134 hv_24x7/pm_pb_cyc,chip=1/ # 2.3 GHz PowerBUS_Frequency_1 2.000314878 9,365,868 hv_24x7/pm_pb_cyc,chip=0/ # 2.3 GHz PowerBUS_Frequency_0 2.000314878 9,366,092 hv_24x7/pm_pb_cyc,chip=1/ # 2.3 GHz PowerBUS_Frequency_1 So, here _0 and _1 after PowerBUS_Frequency specify parameter value.

In the more common per-cpu case, the branch stack is not separated for different threads, instead being cleared in between each sample. That approach will not work very well for adding branch stacks to regular events. The branch stacks really need to be accumulated separately for each thread. As a start to accomplishing that, this patch adds support for putting branch stack support into the thread-stack. The advantages are: 1. the branches are accumulated separately for each thread 2. the branch stack is cleared only in between continuous traces This helps pave the way for adding branch stacks to regular events, not just synthesized events as at present.

There is a mismatch between kernel symbol and address. Here is an example for kernel symbol check_chain_key: 3.55% find /lib/modules/.../build/vmlinux 0xf11ec v [k] check_chain_key This address is off by 0xff000 as can be seen with: [root@t35lp46 ~]# fgrep check_chain_key /proc/kallsyms 00000000001f00d0 t check_chain_key [root@t35lp46 ~]# objdump -t ~/linux/vmlinux| fgrep check_chain_key 00000000001f00d0 l F .text 00000000000001e8 check_chain_key [root@t35lp46 ~]# This function is located in main memory 0x1f00d0 - 0x1f02b4. It has several entries in the perf data file with the correct address: [root@t35lp46 perf]# ./perf report -D -i perf.data.find-bad | \ fgrep SAMPLE| fgrep 0x1f01ec PERF_RECORD_SAMPLE(IP, 0x1): 22228/22228: 0x1f01ec period: 1300000 addr: 0 PERF_RECORD_SAMPLE(IP, 0x1): 22228/22228: 0x1f01ec period: 1300000 addr: 0 The root cause happens when reading symbol tables during perf report. A long gdb call chain leads to machine__deliver_events perf_evlist__deliver_event perf_evlist__deliver_sample build_id__mark_dso_hits thread__find_map(1) Read correct address from sample entry map__load dso__load Some more functions to end up in .... dso__load_sym. Function dso__load_syms checks for kernel relocation and symbol adjustment for the kernel and results in kernel map adjustment of kernel .text segment address (0x100000 on s390) kernel .text segment offset in file (0x1000 on s390). This results in all kernel symbol addresses to be changed by subtracting 0xff000 (on s390). For the symbol check_chain_key we end up with 0x1f00d0 - 0x100000 + 0x1000 = 0xf11d0 and this address is saved in the perf symbol table. This calculation is also applied by the mapping functions map__mapip() and map__unmapip() to map IP addresses to dso mappings. During perf report processing functions process_sample_event (builtin-report.c) machine__resolve thread__find_map hist_entry_iter_add are called. Function thread__find_map(1) takes the correct sample address and applies the mapping function map__mapip() from the kernel dso and saves the modified address in struct addr_location for further reference. From now on this address is used. Funktion process_sample_event() then calls hist_entry_iter_add() to save the address in member ip of struct hist_entry. When samples are displayed using perf_evlist__tty_browse_hists hists__fprintf hist_entry__fprintf hist_entry__snprintf __hist_entry__snprintf _hist_entry__sym_snprintf() This simply displays the address of the symbol and ignores the dso <-> map mappings done in function thread__find_map. This leads to the address mismatch.

This changes kallsyms__parse to use the io library rather than fgets to improve performance of the user code by over 8%. Before: Running 'internals/kallsyms-parse' benchmark: Average kallsyms__parse took: 103.988 ms (+- 0.203 ms) After: Running 'internals/kallsyms-parse' benchmark: Average kallsyms__parse took: 95.571 ms (+- 0.006 ms) For a workload like: $ perf record /bin/true Run under 'perf record -e cycles:u -g' the time goes from: Before 30.10% 1.67% perf perf [.] kallsyms__parse After 25.55% 20.04% perf perf [.] kallsyms__parse So a little under 5% of the start-up time is removed.

Test results:
The first ones are container based builds of tools/perf with and without libelf
support. Where clang is available, it is also used to build perf with/without
libelf, and building with LIBCLANGLLVM=1 (built-in clang) with gcc and clang
when clang and its devel libraries are installed.
The objtool and samples/bpf/ builds are disabled now that I'm switching from
using the sources in a local volume to fetching them from a http server to
build it inside the container, to make it easier to build in a container cluster.
Those will come back later.
Several are cross builds, the ones with -x-ARCH and the android one, and those
may not have all the features built, due to lack of multi-arch devel packages,
available and being used so far on just a few, like
debian:experimental-x-{arm64,mipsel}.
The 'perf test' one will perform a variety of tests exercising
tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf commands
with a variety of command line event specifications to then intercept the
sys_perf_event syscall to check that the perf_event_attr fields are set up as
expected, among a variety of other unit tests.
Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/
with a variety of feature sets, exercising the build with an incomplete set of
features as well as with a complete one. It is planned to have it run on each
of the containers mentioned above, using some container orchestration
infrastructure. Get in contact if interested in helping having this in place.
Ubuntu 19.10 is failing when linking against libllvm, which isn't the default,
needs to be investigated, haven't tested with CC=gcc, but should be the same
problem:

It builds ok with the default set of options.

perf dso: Fix dso comparison (2020-03-24 10:57:38 -0300)
----------------------------------------------------------------
perf/core improvements and fixes:
perf report/top:
Jin Yao:
- Support annotation of unresolved symbols, just using its addresses.
- Print addr_location.al_addr when finding a map but not a symbol, so
that we have the address relative to the map which is what objdump
produces, then we can match the output of perf and objdump for such
unresolved addresses.
- Allow sorting by non-group leaders when working with multiple events,
be it in a explicit group, i.e. an event list surrounded by {} (e.g.
'perf record -e '{cycles,instructions,cache-misses}', or without,
using --group in 'perf report', e.g.:
perf record -e cycles,instructions,cache-misses
perf report --group --group-sort-idx 1
That '1' will ask for the output to be sorted by 'instructions', not
the default 'cycles'.
- Add hotkeys to interactively resort the output when using multiple
events, '0', '1', ... '9' to resort by the nth event, just like when
using --group-sort-idx, as explained above.
perf stat:
Jin Yao:
- Align the output for interval aggregation mode.
event parsing:
Ian Rogers:
- Fix 3 use after frees found with clang ASAN.
perf tools:
Jiri Olsa:
- Unify a bit the build directory output.
perf tests:
John Garry:
- Add PMU events tests, checking that JSON files are properly parsed.
perf stat:
Kajol Jain:
- Fix printing event names of metric group with multiple events incase of overlapping events.
perf symbols:
Leo Yan:
- Consolidate symbol fixup issue.
vendor events AMD:
Vijay Thakkar:
- Restrict model detection for zen1 based processors
- Add Zen2 events.
- Update Zen1 events to V2.
perf cpumap:
Christophe JAILLET:
- Fix snprintf overflow check
DSOs:
Ravi Bangoria:
- Fix dso comparison wrt IDs (maj, min, etc), that had made 'perf archive'
stop working when build-ids were not being collected.

Test results:
The first ones are container based builds of tools/perf with and without libelf
support. Where clang is available, it is also used to build perf with/without
libelf, and building with LIBCLANGLLVM=1 (built-in clang) with gcc and clang
when clang and its devel libraries are installed.
The objtool and samples/bpf/ builds are disabled now that I'm switching from
using the sources in a local volume to fetching them from a http server to
build it inside the container, to make it easier to build in a container cluster.
Those will come back later.
Several are cross builds, the ones with -x-ARCH and the android one, and those
may not have all the features built, due to lack of multi-arch devel packages,
available and being used so far on just a few, like
debian:experimental-x-{arm64,mipsel}.
The 'perf test' one will perform a variety of tests exercising
tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf commands
with a variety of command line event specifications to then intercept the
sys_perf_event syscall to check that the perf_event_attr fields are set up as
expected, among a variety of other unit tests.
Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/
with a variety of feature sets, exercising the build with an incomplete set of
features as well as with a complete one. It is planned to have it run on each
of the containers mentioned above, using some container orchestration
infrastructure. Get in contact if interested in helping having this in place.
Ubuntu 19.10 is failing when linking against libllvm, which isn't the default,
needs to be investigated, haven't tested with CC=gcc, but should be the same
problem:

Test results:
The first ones are container based builds of tools/perf with and without libelf
support. Where clang is available, it is also used to build perf with/without
libelf, and building with LIBCLANGLLVM=1 (built-in clang) with gcc and clang
when clang and its devel libraries are installed.
The objtool and samples/bpf/ builds are disabled now that I'm switching from
using the sources in a local volume to fetching them from a http server to
build it inside the container, to make it easier to build in a container cluster.
Those will come back later.
Several are cross builds, the ones with -x-ARCH and the android one, and those
may not have all the features built, due to lack of multi-arch devel packages,
available and being used so far on just a few, like
debian:experimental-x-{arm64,mipsel}.
The 'perf test' one will perform a variety of tests exercising
tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf commands
with a variety of command line event specifications to then intercept the
sys_perf_event syscall to check that the perf_event_attr fields are set up as
expected, among a variety of other unit tests.
Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/
with a variety of feature sets, exercising the build with an incomplete set of
features as well as with a complete one. It is planned to have it run on each
of the containers mentioned above, using some container orchestration
infrastructure. Get in contact if interested in helping having this in place.
Clearlinux and debian:experimental are failing when due to:
`.gnu.debuglto_.debug_macro' referenced in section `.gnu.debuglto_.debug_macro' of /tmp/build/perf/util/scripting-engines/perf-in.o: defined in discarded section `.gnu.debuglto_.debug_macro[wm4.stdcpredef.h.19.8dc41bed5d9037ff9622e015fb5f0ce3]' of /tmp/build/perf/util/scripting-engines/perf-in.o
Ubuntu 19.10 is failing when linking against libllvm, which isn't the default,
needs to be investigated, haven't tested with CC=gcc, but should be the same problem:

perf block-info: Support color ops to print block percents in color (2020-03-09 21:43:25 -0300)
----------------------------------------------------------------
perf/core improvements and fixes:
perf stat:
Jin Yao:
- Show percore counts in per CPU output.
perf report:
Jin Yao:
- Allow selecting which block info columns to report and its order.
- Support color ops to print block percents in color.
- Fix wrong block address comparison in block_info__cmp().
perf annotate:
Ravi Bangoria:
- Get rid of annotation->nr_jumps, unused.
expr:
Jiri Olsa:
- Move expr lexer to flex.
llvm:
Arnaldo Carvalho de Melo:
- Add debug hint message about missing kernel-devel package.
core:
Kan Liang:
- Initial patches to support the recently added PERF_SAMPLE_BRANCH_HW_INDEX
kernel feature.
- Add check for unexpected use of reserved membrs in event attr, so that in
the future older perf tools will complain instead of silently try to process
unknown features.
libapi:
Namhyung Kim:
- Adopt cgroupsfs_find_mountpoint() from tools/perf/util/.
libperf:
Michael Petlan:
- Add counting example.
libtraceevent:
Steven Rostedt (VMware):
- Remove extra '\n' in print_event_time().

Test results:
The first ones are container based builds of tools/perf with and without libelf
support. Where clang is available, it is also used to build perf with/without
libelf, and building with LIBCLANGLLVM=1 (built-in clang) with gcc and clang
when clang and its devel libraries are installed.
The objtool and samples/bpf/ builds are disabled now that I'm switching from
using the sources in a local volume to fetching them from a http server to
build it inside the container, to make it easier to build in a container cluster.
Those will come back later.
Several are cross builds, the ones with -x-ARCH and the android one, and those
may not have all the features built, due to lack of multi-arch devel packages,
available and being used so far on just a few, like
debian:experimental-x-{arm64,mipsel}.
The 'perf test' one will perform a variety of tests exercising
tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf commands
with a variety of command line event specifications to then intercept the
sys_perf_event syscall to check that the perf_event_attr fields are set up as
expected, among a variety of other unit tests.
Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/
with a variety of feature sets, exercising the build with an incomplete set of
features as well as with a complete one. It is planned to have it run on each
of the containers mentioned above, using some container orchestration
infrastructure. Get in contact if interested in helping having this in place.
Clearlinux is failing when due to:
`.gnu.debuglto_.debug_macro' referenced in section `.gnu.debuglto_.debug_macro' of /tmp/build/perf/util/scripting-engines/perf-in.o: defined in discarded section `.gnu.debuglto_.debug_macro[wm4.stdcpredef.h.19.8dc41bed5d9037ff9622e015fb5f0ce3]' of /tmp/build/perf/util/scripting-engines/perf-in.o
Ubuntu 19.10 is failing when linking against libllvm, which isn't the default,
needs to be investigated, haven't tested with CC=gcc, but should be the same problem:

Test results:
The first ones are container based builds of tools/perf with and without libelf
support. Where clang is available, it is also used to build perf with/without
libelf, and building with LIBCLANGLLVM=1 (built-in clang) with gcc and clang
when clang and its devel libraries are installed.
The objtool and samples/bpf/ builds are disabled now that I'm switching from
using the sources in a local volume to fetching them from a http server to
build it inside the container, to make it easier to build in a container cluster.
Those will come back later.
Several are cross builds, the ones with -x-ARCH and the android one, and those
may not have all the features built, due to lack of multi-arch devel packages,
available and being used so far on just a few, like
debian:experimental-x-{arm64,mipsel}.
The 'perf test' one will perform a variety of tests exercising
tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf commands
with a variety of command line event specifications to then intercept the
sys_perf_event syscall to check that the perf_event_attr fields are set up as
expected, among a variety of other unit tests.
Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/
with a variety of feature sets, exercising the build with an incomplete set of
features as well as with a complete one. It is planned to have it run on each
of the containers mentioned above, using some container orchestration
infrastructure. Get in contact if interested in helping having this in place.
Clearlinux is failing when due to:
`.gnu.debuglto_.debug_macro' referenced in section `.gnu.debuglto_.debug_macro' of /tmp/build/perf/util/scripting-engines/perf-in.o: defined in discarded section `.gnu.debuglto_.debug_macro[wm4.stdcpredef.h.19.8dc41bed5d9037ff9622e015fb5f0ce3]' of /tmp/build/perf/util/scripting-engines/perf-in.o
OpenMandriva Cooker works well with gcc, uncovers a bug where we have to
get compiler-clang.h from the kernel sources, will be fixed soon.
With the update of linux/linkage.h to move from ENTRY()/ENDPROC() to
SYM_FUNC_START()/etc some of the older containers can't be used with clang,
as the minimum version for the constructs used in the new linkage.h is 3.5,
older versions (3.4, 3.4.2, etc) end up with:
bench/../../arch/x86/lib/memcpy_64.S:44:14: error: unexpected token in '.type' directive
.type MEMCPY STT_FUNC ; .size MEMCPY, .-MEMCPY

Ubuntu 19.10 is failing when linking against libllvm, which isn't the default,
needs to be investigated, haven't tested with CC=gcc, but should be the same problem:

tools lib: Fix builds when glibc contains strlcpy() (2020-01-06 11:46:10 -0300)
----------------------------------------------------------------
perf/core improvements and fixes.
perf record:
Alexey Budankov:
- Adapt affinity for machines with #CPUs > 1K to overcome current 1024 CPUs
mask size limitation of cpu_set_t type.
perf report/top TUI:
Arnaldo Carvalho de Melo:
- Make ENTER consistently present the pop up menu with and without call
chains, to eliminate confusion. The menu continues available at all times
use 'm' and '+' can be used to toggle just one call chain level, 'e' for all
the call chains for a top level histogram entry and 'E' to expand all call
chains in all top level entries. Extra info about these options was added to
the pop up menu entries. Pressing 'k' serves as special hotkey to go straight
to the main vmlinux entries, to avoid having to press enter and then select
"Zoom into the kernel DSO".
perf sched timehist:
David Ahern:
- Add support for filtering on CPU.
perf tests:
Arnaldo Carvalho de Melo:
- Show expected versus obtained values in bp_signal test.
libperf:
Jiri Olsa:
- Move to tools/lib/perf.
- Add man pages.
libapi:
Andrey Zhizhikin:
- Fix gcc9 stringop-truncation compilation error.
tools lib:
Vitaly Chikunov:
- Fix builds when glibc contains strlcpy(), which is the case for ALT Linux.

Test results:
The first ones are container based builds of tools/perf with and without libelf
support. Where clang is available, it is also used to build perf with/without
libelf, and building with LIBCLANGLLVM=1 (built-in clang) with gcc and clang
when clang and its devel libraries are installed.
The objtool and samples/bpf/ builds are disabled now that I'm switching from
using the sources in a local volume to fetching them from a http server to
build it inside the container, to make it easier to build in a container cluster.
Those will come back later.
Several are cross builds, the ones with -x-ARCH and the android one, and those
may not have all the features built, due to lack of multi-arch devel packages,
available and being used so far on just a few, like
debian:experimental-x-{arm64,mipsel}.
The 'perf test' one will perform a variety of tests exercising
tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf commands
with a variety of command line event specifications to then intercept the
sys_perf_event syscall to check that the perf_event_attr fields are set up as
expected, among a variety of other unit tests.
Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/
with a variety of feature sets, exercising the build with an incomplete set of
features as well as with a complete one. It is planned to have it run on each
of the containers mentioned above, using some container orchestration
infrastructure. Get in contact if interested in helping having this in place.
Clearlinux is failing when due to:
`.gnu.debuglto_.debug_macro' referenced in section `.gnu.debuglto_.debug_macro' of /tmp/build/perf/util/scripting-engines/perf-in.o: defined in discarded section `.gnu.debuglto_.debug_macro[wm4.stdcpredef.h.19.8dc41bed5d9037ff9622e015fb5f0ce3]' of /tmp/build/perf/util/scripting-engines/perf-in.o
OpenMandriva Cooker works well with gcc, uncovers a bug where we have to
get compiler-clang.h from the kernel sources, will be fixed soon.
With the update of linux/linkage.h to move from ENTRY()/ENDPROC() to
SYM_FUNC_START()/etc some of the older containers can't be used with clang,
as the minimum version for the constructs used in the new linkage.h is 3.5,
older versions (3.4, 3.4.2, etc) end up with:
bench/../../arch/x86/lib/memcpy_64.S:44:14: error: unexpected token in '.type' directive
.type MEMCPY STT_FUNC ; .size MEMCPY, .-MEMCPY

libtraceevent: Copy pkg-config file to output folder when using O= (2019-12-02 21:58:20 -0300)
----------------------------------------------------------------
perf/core improvements and fixes:
perf report/top:
- Fix segfault due to missing initialization of recently introduced
struct map_symbol 'maps' field in append_inlines(), when running
with DWARF callchains.
perf stat:
Andi Kleen:
- Affinity based optimizations for sessions with many events in
machines with large core counts, avoiding excessive number of IPIs.
libtraceevent:
- Sudip Mukherjee:
- Fix installation with O=.
- Copy pkg-config file to output folder when using O=.
perf bench:
Arnaldo Carvalho de Melo:
- Update the copies of x86's mem{cpy,set}_64.S, and because that
now uses new stuff in linux/linkage.h, update that header too, which
made the minimal clang version to build perf to be 3.5, as
3.4 as found in some of the container images used to test build perf
can't grok STT_FUNC as a token in .type lines.
ABI headers:
Arnaldo Carvalho de Melo:
- Sync x86's msr-index.h copy with the kernel sources, resulting
in new MSRs to be usable in filter expressions in 'perf trace',
such as IA32_TSX_CTRL.
- Sync linux/fscrypt.h, linux/stat.h, sched.h and the kvm headers.
perf trace:
Arnaldo Carvalho de Melo:
- Add CLEAR_SIGHAND support for clone's flags arg
perf kvm:
Arnaldo Carvalho de Melo:
- Clarify the 'perf kvm' -i and -o command line options
perf test:
Ian Rogers:
- Move test functionality in to a 'perf test' entry.

Test results:
The first ones are container based builds of tools/perf with and without libelf
support. Where clang is available, it is also used to build perf with/without
libelf, and building with LIBCLANGLLVM=1 (built-in clang) with gcc and clang
when clang and its devel libraries are installed.
The objtool and samples/bpf/ builds are disabled now that I'm switching from
using the sources in a local volume to fetching them from a http server to
build it inside the container, to make it easier to build in a container cluster.
Those will come back later.
Several are cross builds, the ones with -x-ARCH and the android one, and those
may not have all the features built, due to lack of multi-arch devel packages,
available and being used so far on just a few, like
debian:experimental-x-{arm64,mipsel}.
The 'perf test' one will perform a variety of tests exercising
tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf commands
with a variety of command line event specifications to then intercept the
sys_perf_event syscall to check that the perf_event_attr fields are set up as
expected, among a variety of other unit tests.
Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/
with a variety of feature sets, exercising the build with an incomplete set of
features as well as with a complete one. It is planned to have it run on each
of the containers mentioned above, using some container orchestration
infrastructure. Get in contact if interested in helping having this in place.
Clearlinux is failing when building with libpython, but that is not a perf
regression, will try to remove one compiler warning that is causing the problem
when building some of the glue code files in the python files, outside perf.
OpenMandriva Cooker works well with gcc, uncovers a bug where we have to
get compiler-clang.h from the kernel sources, will be fixed soon.
With the update of linux/linkage.h to move from ENTRY()/ENDPROC() to
SYM_FUNC_START()/etc some of the older containers can't be used with clang,
as the minimum version for the constructs used in the new linkage.h is 3.5,
older versions (3.4, 3.4.2, etc) end up with:
bench/../../arch/x86/lib/memcpy_64.S:44:14: error: unexpected token in '.type' directive
.type MEMCPY STT_FUNC ; .size MEMCPY, .-MEMCPY
^
Finally the build-tests and container tests were performed with the following
two fixes (different sha, same contents), that are not in this patch series,
will go thru the bpf/net trees.
The 'perf test' was performed with what is in this series tho.

Hi Ingo/Thomas,
Please consider pulling, this has a merge with mainline to pick
bpf stuff, and the build-test and container build tests were performed
with two extra patches I cooked to fix libbpf issuers in some odd 32-bit
arches and on generation of some bpf helpers headers that will hit
mainline via the bpf/net trees.
Best regards,
- Arnaldo

Test results:
The first ones are container based builds of tools/perf with and without libelf
support. Where clang is available, it is also used to build perf with/without
libelf, and building with LIBCLANGLLVM=1 (built-in clang) with gcc and clang
when clang and its devel libraries are installed.
The objtool and samples/bpf/ builds are disabled now that I'm switching from
using the sources in a local volume to fetching them from a http server to
build it inside the container, to make it easier to build in a container cluster.
Those will come back later.
Several are cross builds, the ones with -x-ARCH and the android one, and those
may not have all the features built, due to lack of multi-arch devel packages,
available and being used so far on just a few, like
debian:experimental-x-{arm64,mipsel}.
The 'perf test' one will perform a variety of tests exercising
tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf commands
with a variety of command line event specifications to then intercept the
sys_perf_event syscall to check that the perf_event_attr fields are set up as
expected, among a variety of other unit tests.
Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/
with a variety of feature sets, exercising the build with an incomplete set of
features as well as with a complete one. It is planned to have it run on each
of the containers mentioned above, using some container orchestration
infrastructure. Get in contact if interested in helping having this in place.
Clearlinux is failing when building with libpython, but that is not a perf
regression, will try to remove one compiler warning that is causing the problem
when building some of the glue code files in the python files, outside perf.
OpenMandriva Cooker works well with gcc, uncovers a bug where we have to
get compiler-clang.h from the kernel sources, will be fixed soon.
Finally the build-tests and container tests were performed with the following
two fixes, that are not in this patch series, will go thru the bpf/net trees:
$ git log --oneline -2
e1bc15a8e7d1 (HEAD -> perf/core) libbpf: Use PRIu64 for sym->st_value to fix build on 32-bit arches
0d0f9df96c5a libbpf: Fix up generation of bpf_helper_defs.h
$
The 'perf test' was performed with what is in this series tho.

perf parse: Fix potential memory leak when handling tracepoint errors (2019-11-22 10:48:14 -0300)
----------------------------------------------------------------
perf/core improvements and fixes:
perf report:
Jin Yao:
- Allow entering the annotation view (symbol source/assembly +
overhead/cycles/etc column) from the 'perf report --total-cycles'
interface.
E.g.:
# perf record --all-cpus --branch-any --all-kernel
^C[ perf record: Woken up 5 times to write data ]
#
# perf evlist -v
cycles: size: 120, { sample_period, sample_freq }: 4000,

Then press 'A' or Enter on one of those lines, just like with 'perf top', say

We need to improve this to show the source code line numbers in the
annotation view, so one can go from that program block to the annotation view
and see those source code line numbers straight away.
auxtrace/Intel PT:
Adrian Hunter:
- Add support for AUX area sampling, requires new functionality that
will land in 5.5, its already in tip.
This includes kernel capability querying so that it fails gracefully
with older kernels, duimping aux area samples in 'perf report -D' and
'perf script'.
perf.data:
Alexey Budankov:
- Fix decompression of PERF_RECORD_COMPRESSED records.
core:
Arnaldo Carvalho de Melo:
- Use the 'dcacheline' cmp routine to find the right DSOs taking into
account the 'maj', 'min', 'ino' and 'ino_generation', that got moved
from 'struct map' to 'struct dso', where it belongs.
This further reduces the size of 'struct map', there is still more
work to do to maybe get it to max one cacheline.
libtraceevent:
Hewenliang:
- Fix memory leakage in copy_filter_type().
Sudip Mukherjee:
- Fix header installation.
perf parse:
Ian Rogers :
- Fix potential memory leak when handling tracepoint errors, found using
LLVM's libFuzzer.
perf probe:
Colin Ian King:
- Fix spelling mistake "addrees" -> "address".

Test results:
The first ones are container based builds of tools/perf with and without libelf
support. Where clang is available, it is also used to build perf with/without
libelf, and building with LIBCLANGLLVM=1 (built-in clang) with gcc and clang
when clang and its devel libraries are installed.
The objtool and samples/bpf/ builds are disabled now that I'm switching from
using the sources in a local volume to fetching them from a http server to
build it inside the container, to make it easier to build in a container cluster.
Those will come back later.
Several are cross builds, the ones with -x-ARCH and the android one, and those
may not have all the features built, due to lack of multi-arch devel packages,
available and being used so far on just a few, like
debian:experimental-x-{arm64,mipsel}.
The 'perf test' one will perform a variety of tests exercising
tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf commands
with a variety of command line event specifications to then intercept the
sys_perf_event syscall to check that the perf_event_attr fields are set up as
expected, among a variety of other unit tests.
Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/
with a variety of feature sets, exercising the build with an incomplete set of
features as well as with a complete one. It is planned to have it run on each
of the containers mentioned above, using some container orchestration
infrastructure. Get in contact if interested in helping having this in place.
Clearlinux is failing when building with libpython, but that is not a perf
regression, will try to remove one compiler warning that is causing the problem
when building some of the glue code files in the python files, outside perf.
Manjaro got fixed by adding the 'gettext' package, that provides a
library needed by bison but not present in its dependencies list, i.e. a
distro bug.
cooker is failing with:

Still needs investigating, new image, just leaving it here for

perf parse: Report initial event parsing error (2019-11-18 19:14:29 -0300)
----------------------------------------------------------------
perf/core improvements and fixes:
x86/insn:
Adrian Hunter:
- Add some more Intel instructions to the opcode map:
cldemote, encls, enclu, enclv, enqcmd, enqcmds, movdir64b,
movdiri, pconfig, tpause, umonitor, umwait, wbnoinvd.
- The instruction decoding can be tested using the perf tools'
"x86 instruction decoder - new instructions" test as folllows:
$ perf test -v "new " 2>&1 | grep -i cldemote
Decoded ok: 0f 1c 00 cldemote (%eax)
Decoded ok: 0f 1c 05 78 56 34 12 cldemote 0x12345678
Decoded ok: 0f 1c 84 c8 78 56 34 12 cldemote 0x12345678(%eax,%ecx,8)
Decoded ok: 0f 1c 00 cldemote (%rax)
Decoded ok: 41 0f 1c 00 cldemote (%r8)
Decoded ok: 0f 1c 04 25 78 56 34 12 cldemote 0x12345678
Decoded ok: 0f 1c 84 c8 78 56 34 12 cldemote 0x12345678(%rax,%rcx,8)
Decoded ok: 41 0f 1c 84 c8 78 56 34 12 cldemote 0x12345678(%r8,%rcx,8)
$ perf test -v "new " 2>&1 | grep -i tpause
Decoded ok: 66 0f ae f3 tpause %ebx
Decoded ok: 66 0f ae f3 tpause %ebx
Decoded ok: 66 41 0f ae f0 tpause %r8d
callchains:
Adrian Hunter:
- Fix segfault in thread__resolve_callchain_sample().
perf probe:
- Line fixes to show only lines where probes can be used with 'perf probe -L',
and when reporting them via 'perf probe -l'.
- Support multiprobe events.
perf scripts python:
Adrian Hunter:
- Fix use of TRUE with SQLite < 3.23 in exported-sql-viewer.py.
perf maps:
- Trim 'struct map' by removing the rb_node member for sorting
by map name, as that is only needed for processing kernel maps,
and only when classifying symbols by section at load time.
Sort them by name using qsort() and do lookups using bsearch()
when map_groups__find_by_name() is used.
perf parse:
Ian Rogers:
- Report initial event parsing error, providing a less cryptic message
to state that a PMU wasn't found in the system.
perf vendor events:
James Clark:
- Fix commas so that PMU event files for arm64, power8 and power nine
become valid JSON.
libtraceevent:
Konstantin Khlebnikov:
- Fix parsing of event %o and %X argument types.

perf parse: Use YYABORT to clear stack after failure, plugging leaks (2019-11-12 08:34:16 -0300)
----------------------------------------------------------------
perf/core improvements and fixes:
perf record:
Ravi Bangoria:
- Provide an option to print perf_event_open args and syscall return value.
This was already possible using -v, but then lots of other debug info
would be output as well, provide a way to show just the syscall args
and return value, e.g.:
# perf --debug perf-event-open=1 record
perf_event_attr:
size 112
{ sample_period, sample_freq } 4000
sample_type IP|TID|TIME|PERIOD
read_format ID
disabled 1
inherit 1
<SNIP>
ksymbol 1
bpf_event 1
------------------------------------------------------------
sys_perf_event_open: pid 4308 cpu 0 group_fd -1 flags 0x8 = 4
core:
- Remove map->groups, we can get that information in other ways, reduces
the size of a key data structure and paves the way to have it shared
by multiple threads.
- Use 'struct map_symbol' in more places, where we already were using a
'struct map' + 'struct symbol', this helps passing that usual pair of
information across callchain, browser code, etc.
- Add 'struct map_groups' (where the map_symbol->map is) to 'struct map_symbol',
to ease annotation code, for instance, where we call from functions in one map
we're browsing to functions in another DSO, mapped in another 'struct map'.
event parsing:
Ian Rogers:
- Use YYABORT to clear stack after failure, plugging leaks
Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
----------------------------------------------------------------
Arnaldo Carvalho de Melo (13):
perf map: Use map->dso->kernel + map__kmaps() in map__kmaps()
perf symbols: Stop using map->groups, we can use kmaps instead
perf map_groups: Pass the object to map_groups__find_ams()
perf tools: Add map_groups to 'struct addr_location'
perf annotate: Pass a 'map_symbol' in places receiving a pair of 'map' and 'symbol' pointers
perf unwind: Use 'struct map_symbol' in 'struct unwind_entry'
perf callchain: Use 'struct map_symbol' in 'struct callchain_cursor_node'
pref tools: Make 'struct addr_map_symbol' contain 'struct map_symbol'
perf symbols: Use kmaps(map)->machine when we know its a kernel map
perf tools: Add a 'struct map_groups' pointer to 'struct map_symbol'
perf annotate: Stop using map->groups, use map_symbol->mg instead
perf map: Combine maps__fixup_overlappings with its only use
perf map: Remove ->groups from 'struct map'
Ian Rogers (1):
perf parse: Use YYABORT to clear stack after failure, plugging leaks

Test results:
The first ones are container based builds of tools/perf with and without libelf
support. Where clang is available, it is also used to build perf with/without
libelf, and building with LIBCLANGLLVM=1 (built-in clang) with gcc and clang
when clang and its devel libraries are installed.
The objtool and samples/bpf/ builds are disabled now that I'm switching from
using the sources in a local volume to fetching them from a http server to
build it inside the container, to make it easier to build in a container cluster.
Those will come back later.
Several are cross builds, the ones with -x-ARCH and the android one, and those
may not have all the features built, due to lack of multi-arch devel packages,
available and being used so far on just a few, like
debian:experimental-x-{arm64,mipsel}.
The 'perf test' one will perform a variety of tests exercising
tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf commands
with a variety of command line event specifications to then intercept the
sys_perf_event syscall to check that the perf_event_attr fields are set up as
expected, among a variety of other unit tests.
Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/
with a variety of feature sets, exercising the build with an incomplete set of
features as well as with a complete one. It is planned to have it run on each
of the containers mentioned above, using some container orchestration
infrastructure. Get in contact if interested in helping having this in place.
Clearlinux is failing when building with libpython, but that is not a perf
regression, will try to remove one compiler warning that is causing the problem
when building some of the glue code files in the python files, outside perf.
Manjaro is failing due to some missing library related to bison, looks like
a distro bug.

perf report: Sort by sampled cycles percent per block for tui (2019-11-07 10:14:48 -0300)
----------------------------------------------------------------
perf/core improvements and fixes:
perf report:
Jin Yao:
- Introduce --total-cycles, for basic block profiling, further using data
obtained from LBR, an example should suffice:
# perf record -b
^C[ perf record: Woken up 595 times to write data ]
[ perf record: Captured and wrote 156.672 MB perf.data (196873 samples) ]
# perf evlist -v
cycles: size: 112, { sample_period, sample_freq }: 4000, sample_type: IP|TID|TIME|CPU|PERIOD|BRANCH_STACK, read_format: ID, disabled: 1, inherit: 1, mmap: 1, comm: 1, freq: 1, task: 1, precise_ip: 3, sample_id_all: 1, exclude_guest: 1, mmap2: 1, comm_exec: 1, ksymbol: 1, bpf_event: 1, branch_sample_type: ANY
# perf report --total-cycles --stdio
# To display the perf.data header info, please use --header/--header-only options.

perf record:
Adrian Hunter:
- Allow storing perf.data in a directory together with a copy of /proc/kcore.
Jiwei Sun:
- Add support for limit perf output file size, i.e.:
# perf record --all-cpus -F 10000 --max-size=4M sleep 10h
[ perf record: perf size limit reached (4097 KB), stopping session ]
[ perf record: Woken up 6 times to write data ]
[ perf record: Captured and wrote 4.048 MB perf.data (54094 samples) ]
Terminated
# ls -lah perf.data
-rw-------. 1 root root 4.1M Nov 7 15:27 perf.data
#
perf stat:
Jiri Olsa:
- Add --per-node agregation support:
In live mode:
# perf stat -a -I 1000 -e cycles --per-node
# time node cpus counts unit events
1.000542550 N0 20 6,202,097 cycles

3.003451699 N0 20 6,508,917 cycles
3.003451699 N1 20 765,607 cycles

...
perf probe:
Masami Hiramatsu:
Various fixes related to recent additions to the DWARF format:
- Fix to find range-only function instance
- Walk function lines in lexical blocks
- Fix to show function entry line as probe-able
- Fix wrong address verification
- Fix to probe a function which has no entry pc
- Fix to probe an inline function which has no entry pc
- Fix to list probe event with correct line number
- Fix to show inlined function callsite without entry_pc
- Fix to show ranges of variables in functions without entry_pc
- Return a better scope DIE if there is no best scope
- Skip end-of-sequence and non statement lines
- Filter out instances except for inlined subroutine and subprogram
- Fix to show calling lines of inlined functions
- Skip overlapped location on searching variables
perf inject:
Adrian Hunter:
- Do not strip evsels with --strip, as they are needed for create_gcov
(see the autofdo example in tools/perf/Documentation/intel-pt.txt).
Intel PT:
Adrian Hunter:
- Intel PT uses an auxtrace_cache to store the results of code-walking, to avoid
repeated decoding. Add an auxtrace_cache__remove to handle text poke events.
core:
Andi Kleen:
- Always preserve errno while cleaning up perf_event_open failures.
llvm:

Test results:
The first ones are container based builds of tools/perf with and without libelf
support. Where clang is available, it is also used to build perf with/without
libelf, and building with LIBCLANGLLVM=1 (built-in clang) with gcc and clang
when clang and its devel libraries are installed.
The objtool and samples/bpf/ builds are disabled now that I'm switching from
using the sources in a local volume to fetching them from a http server to
build it inside the container, to make it easier to build in a container cluster.
Those will come back later.
Several are cross builds, the ones with -x-ARCH and the android one, and those
may not have all the features built, due to lack of multi-arch devel packages,
available and being used so far on just a few, like
debian:experimental-x-{arm64,mipsel}.
The 'perf test' one will perform a variety of tests exercising
tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf commands
with a variety of command line event specifications to then intercept the
sys_perf_event syscall to check that the perf_event_attr fields are set up as
expected, among a variety of other unit tests.
Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/
with a variety of feature sets, exercising the build with an incomplete set of
features as well as with a complete one. It is planned to have it run on each
of the containers mentioned above, using some container orchestration
infrastructure. Get in contact if interested in helping having this in place.
Clearlinux is failing when building with libpython, but that is not a perf
regression, will try to remove one compiler warning that is causing the problem
when building some of the glue code files in the python files, outside perf.
Manjaro is failing due to some missing library related to bison, looks like
a distro bug.

perf trace: Use STUL_STRARRAY_FLAGS with mmap (2019-10-19 15:35:02 -0300)
----------------------------------------------------------------
perf/core improvements and fixes:
perf trace:
- Add syscall failure stats to -s/--summary and -S/--with-summary, also works in
combination with specifying just a set of syscalls, see below first with
-s/--summary, then with -S/--with-summary just for the syscalls we saw failing
with -s:

- Add a generator for x86's IRQ vectors -> strings
- Introduce stroul() (string -> number) methods for the strarray and
strarrays classes, also strtoul_flags, allowing to go from both strings
and or-ed strings to numbers, allowing things like:
# perf trace -e syscalls:sys_enter_mmap --filter="flags==DENYWRITE|PRIVATE|FIXED" sleep 1
0.000 sleep/22588 syscalls:sys_enter_mmap(addr: 0x7f42d2aa5000, len: 1363968, prot: READ|EXEC, flags: PRIVATE|FIXED|DENYWRITE, fd: 3, off: 0x22000)

perf annotate:
- Fix objdump --no-show-raw-insn flag to work with goth gcc and clang.
- Streamline objdump execution, preserving the right error codes for better
reporting to user.
perf report:
- Add warning when libunwind not compiled in.
perf stat:
Jin Yao:
- Support --all-kernel/--all-user, to match options available in 'perf record',
asking that all the events specified work just with kernel or user events.
perf list:
Jin Yao:
- Hide deprecated events by default, allow showing them with --deprecated.
libbperf:
Jiri Olsa:
- Allow to build with -ltcmalloc.
- Finish mmap interface, getting more stuff from tools/perf while adding
abstractions to avoid pulling too much stuff, to get libperf to grow as
tools needs things like auxtrace, etc.
perf scripting engines:
Steven Rostedt (VMware):
- Iterate on tep event arrays directly, fixing script generation with
'-g python' when having multiple tracepoints in a perf.data file.
core:
- Allow to build with -ltcmalloc.
perf test:
Leo Yan:
- Report failure for mmap events.
- Avoid infinite loop for task exit case.
- Remove needless headers for bp_account test.
- Add dedicated checking helper is_supported().
- Disable bp_signal testing for arm64.
Vendor events:
arm64:
John Garry:
- Fix Hisi hip08 DDRC PMU eventname.
- Add some missing events for Hisi hip08 DDRC, L3C and HHA PMUs.

Test results:
The first ones are container based builds of tools/perf with and without libelf
support. Where clang is available, it is also used to build perf with/without
libelf, and building with LIBCLANGLLVM=1 (built-in clang) with gcc and clang
when clang and its devel libraries are installed.
The objtool and samples/bpf/ builds are disabled now that I'm switching from
using the sources in a local volume to fetching them from a http server to
build it inside the container, to make it easier to build in a container cluster.
Those will come back later.
Several are cross builds, the ones with -x-ARCH and the android one, and those
may not have all the features built, due to lack of multi-arch devel packages,
available and being used so far on just a few, like
debian:experimental-x-{arm64,mipsel}.
The 'perf test' one will perform a variety of tests exercising
tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf commands
with a variety of command line event specifications to then intercept the
sys_perf_event syscall to check that the perf_event_attr fields are set up as
expected, among a variety of other unit tests.
Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/
with a variety of feature sets, exercising the build with an incomplete set of
features as well as with a complete one. It is planned to have it run on each
of the containers mentioned above, using some container orchestration
infrastructure. Get in contact if interested in helping having this in place.
Clearlinux is failing when building with libpython, but that is not a perf
regression, will try to remove one compiler warning that is causing the problem
when building some of the glue code files in the python files, outside perf.

----------------------------------------------------------------
perf/core improvements and fixes:
perf trace:
Arnaldo Carvalho de Melo:
- Reuse the strace-like syscall_arg_fmt->scnprintf() beautification routines
(convert integer arguments into strings, like open flags, etc) in tracepoint
arguments.
For now the type based scnprintf routines (pid_t, umode_t, etc) and the
ones based in well known arg name based ("fd", etc) gets associated with
tracepoint args of that type.
A tracepoint only arg, "msr", for the msr:{write,read}_msr gets added as
an initial step.
- Introduce syscall_arg_fmt->strtoul() methods to be the reverse operation
of ->scnprintf(), i.e. to go from a string to an integer.
- Implement --filter, just like in 'perf record', that affects the tracepoint
events specied thus far in the command line, use the ->strtoul() methods
to allow strings in tables associated with beautifiers to the integers
the in-kernel tracepoint (eBPF later) filters expect, e.g.:
# perf trace --max-events 1 -e sched:*ipi --filter="cpu==1 || cpu==2"
0.000 as/24630 sched:sched_wake_idle_without_ipi(cpu: 1)
#
# perf trace --max-events 1 --max-stack=32 -e msr:* --filter="msr==IA32_TSC_DEADLINE"

- Default to not using libtraceevent and its plugins for beautifying
tracepoint arguments, since now we're reusing the strace-like beautifiers.
Use --libtraceevent_print (using just --libtrace is unambiguous and can
be used as a short hand) to go back to those beautifiers.
This will help in the transition, as can be seen in some of the sched tracepoints
that still need some work in the libbeauty based mode:

- Make -v (verbose) mode be honoured for .perfconfig based trace.add_events,
to help in diagnosing problems with building eBPF events (-e source.c).
- When using eBPF syscall payload augmentation do not show strace-like
syscalls when all the user specified was some tracepoint event, bringing
the behaviour in line with that of when not using eBPF augmentation.
Intel PT:
exported-sql-viewer GUI:
Adrian Hunter:
- Add LookupModel, HBoxLayout, VBoxLayout, global time range calculations
so as to add a time chart by CPU.
perf script:
Andi Kleen:
- Allow --time (to specify a time span of interest) with --reltime
perf diff:
Jin Yao:
- Report noise for cycles diff, i.e. a histogram + stddev.
(timestamps relative to start).
perf annotate:
Arnaldo Carvalho de Melo:
- Initialize env->cpuid when running in live mode (perf top), as it
is used in some of the per arch annotation init routines.
samples bpf:
Björn Töpel:
- Fixup fallout of using tools/perf/perf-sys. from outside tools/perf.
Core:
Ian Rogers:
- Avoid 'sample_reg_masks' being const + weak, as this breaks with some
compilers that constant-propagate from the weak symbol.
libperf:
- First part of moving the perf_mmap class from tools/perf to libperf.
- Propagate CFLAGS to libperf from the tools/perf Makefile.
Vendor events:
John Garry:
- Add entry in MAINTAINERS with reviewers for the for perf tool arm64
pmu-events files.

Test results:
The first ones are container based builds of tools/perf with and without libelf
support. Where clang is available, it is also used to build perf with/without
libelf, and building with LIBCLANGLLVM=1 (built-in clang) with gcc and clang
when clang and its devel libraries are installed.
The objtool and samples/bpf/ builds are disabled now that I'm switching from
using the sources in a local volume to fetching them from a http server to
build it inside the container, to make it easier to build in a container cluster.
Those will come back later.
Several are cross builds, the ones with -x-ARCH and the android one, and those
may not have all the features built, due to lack of multi-arch devel packages,
available and being used so far on just a few, like
debian:experimental-x-{arm64,mipsel}.
The 'perf test' one will perform a variety of tests exercising
tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf commands
with a variety of command line event specifications to then intercept the
sys_perf_event syscall to check that the perf_event_attr fields are set up as
expected, among a variety of other unit tests.
Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/
with a variety of feature sets, exercising the build with an incomplete set of
features as well as with a complete one. It is planned to have it run on each
of the containers mentioned above, using some container orchestration
infrastructure. Get in contact if interested in helping having this in place.
Clearlinux is failing when building with libpython, but that is not a perf
regression, will try to remove one compiler warning that is causing the problem
when building some of the glue code files in the python files, outside perf.

perf parser: Remove needless include directives (2019-09-25 16:26:41 -0300)
----------------------------------------------------------------
perf/core improvements and fixes:
perf record:
Stephane Eranian:
- Fix priv level with branch sampling for paranoid=2, i.e. the kernel checks
if perf_event_attr_attr.exclude_hv is set in addition to .exclude_kernel,
so reset both to zero.
Arnaldo Carvalho de Melo:
- Don't warn about not being able to read kernel maps (kallsyms, etc) when
kernel samples aren't being collected.
perf list:
Kim Phillips:
- Allow plurals for metric, metricgroup., i.e.:
$ perf list metrics
was showing nothing, which is very confusing, make it work like:
$ perf stat metric
perf stat:
Andi Kleen:
- Free memory access/leaks detected via valgrind, related to metrics.
Libraries:
libperf:
Jiri Olsa:
- Move more stuff from tools/perf, this time a first stab at moving perf_mmap
methods.
libtracevent:
Steven Rostedt (VMware):
- Round up in tep_print_event() time precision.
Tzvetomir Stoyanov (VMware):
- Man pages for event print and related and plugins APIs.
- Move traceevent plugins in its own subdirectory.
Feature detection:
Thomas Richter:
- Add detection of java-11-openjdk-devel package, in addition to the older
versions supported.
Architecture specific:
S/390:
Thomas Richter (2):
- Include JVMTI support for s390
Vendor events:
AMD:
Kim Phillips:
- Add L3 cache events for Family 17h.
- Remove redundant '['.
PowerPC:
Mamatha Inamdar:
- Remove P8 HW events which are not supported.
Cleanups:
Arnaldo Carvalho de Melo:
- Remove needless headers, add needed ones, move things around to reduce the
headers dependency tree, speeding up builds by not doing needless compiles
when unrelated stuff gets changed.
- Ditch unused code that was dragging headers.

Test results:
The first ones are container based builds of tools/perf with and without libelf
support. Where clang is available, it is also used to build perf with/without
libelf, and building with LIBCLANGLLVM=1 (built-in clang) with gcc and clang
when clang and its devel libraries are installed.
The objtool and samples/bpf/ builds are disabled now that I'm switching from
using the sources in a local volume to fetching them from a http server to
build it inside the container, to make it easier to build in a container cluster.
Those will come back later.
Several are cross builds, the ones with -x-ARCH and the android one, and those
may not have all the features built, due to lack of multi-arch devel packages,
available and being used so far on just a few, like
debian:experimental-x-{arm64,mipsel}.
The 'perf test' one will perform a variety of tests exercising
tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf commands
with a variety of command line event specifications to then intercept the
sys_perf_event syscall to check that the perf_event_attr fields are set up as
expected, among a variety of other unit tests.
Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/
with a variety of feature sets, exercising the build with an incomplete set of
features as well as with a complete one. It is planned to have it run on each
of the containers mentioned above, using some container orchestration
infrastructure. Get in contact if interested in helping having this in place.
Clearlinux is failing when building with libpython, but that is not a perf
regression, will try to remove one compiler warning that is causing the problem
when building some of the glue code files in the python files, outside perf.

perf kvm stat: Set 'trace_cycles' as default event for 'perf kvm record' in powerpc (2019-09-20 10:28:26 -0300)
----------------------------------------------------------------
perf/core improvements and fixes:
perf stat:
Srikar Dronamraju:
- Fix a segmentation fault when using repeat forever.
- Reset previous counts on repeat with interval.
aarch64:
James Clark:
- Add PMU event JSON files for Cortex-A76 and Neoverse N1.
PowerPC:
Anju T Sudhakar:
- Make 'trace_cycles' the default event for 'perf kvm record' in PowerPC.
S/390:
- Link libjvmti to tools/lib/string.o to have a weak strlcpy()
implementation, providing previously unresolved symbol on s/390.
perf test:
Jiri Olsa:
- Add libperf automated tests to 'make -C tools/perf build-test'.
Colin Ian King:
- Fix spelling mistake.
Tree wide:
Arnaldo Carvalho de Melo:
- Some more header file sanitization.
libperf:
Jiri Olsa:
- Add dependency on libperf for python.so binding.

Test results:
The first ones are container based builds of tools/perf with and without libelf
support. Where clang is available, it is also used to build perf with/without
libelf, and building with LIBCLANGLLVM=1 (built-in clang) with gcc and clang
when clang and its devel libraries are installed.
The objtool and samples/bpf/ builds are disabled now that I'm switching from
using the sources in a local volume to fetching them from a http server to
build it inside the container, to make it easier to build in a container cluster.
Those will come back later.
Several are cross builds, the ones with -x-ARCH and the android one, and those
may not have all the features built, due to lack of multi-arch devel packages,
available and being used so far on just a few, like
debian:experimental-x-{arm64,mipsel}.
The 'perf test' one will perform a variety of tests exercising
tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf commands
with a variety of command line event specifications to then intercept the
sys_perf_event syscall to check that the perf_event_attr fields are set up as
expected, among a variety of other unit tests.
Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/
with a variety of feature sets, exercising the build with an incomplete set of
features as well as with a complete one. It is planned to have it run on each
of the containers mentioned above, using some container orchestration
infrastructure. Get in contact if interested in helping having this in place.
Clearlinux is failing when building with libpython, but that is not a perf
regression, will try to remove one compiler warning that is causing the problem
when building some of the glue code files in the python files, outside perf.

Test results:
The first ones are container based builds of tools/perf with and without libelf
support. Where clang is available, it is also used to build perf with/without
libelf, and building with LIBCLANGLLVM=1 (built-in clang) with gcc and clang
when clang and its devel libraries are installed.
The objtool and samples/bpf/ builds are disabled now that I'm switching from
using the sources in a local volume to fetching them from a http server to
build it inside the container, to make it easier to build in a container cluster.
Those will come back later.
Several are cross builds, the ones with -x-ARCH and the android one, and those
may not have all the features built, due to lack of multi-arch devel packages,
available and being used so far on just a few, like
debian:experimental-x-{arm64,mipsel}.
The 'perf test' one will perform a variety of tests exercising
tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf commands
with a variety of command line event specifications to then intercept the
sys_perf_event syscall to check that the perf_event_attr fields are set up as
expected, among a variety of other unit tests.
Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/
with a variety of feature sets, exercising the build with an incomplete set of
features as well as with a complete one. It is planned to have it run on each
of the containers mentioned above, using some container orchestration
infrastructure. Get in contact if interested in helping having this in place.
Clearlinux is failing when building with libpython, but that is not a perf
regression, will try to remove one compiler warning that is causing the problem
when building some of the glue code files in the python files, outside perf.

tools lib traceevent: Remove unneeded qsort and uses memmove instead (2019-08-29 08:36:12 -0300)
----------------------------------------------------------------
perf/core improvements and fixes:
perf top:
Namhyung Kim:
- Decay all events in the evlist, we were decaying just the first event
in a group.
- Fix linking of histograms in different evsels in a event group with more
than two events.
With the two fixes above a command line such as:
# perf top -e '{cycles,instructions,cache-misses,cache-references}
Should work as expected, with four columns and with all of them being
decayed over time, i.e. less weight is given for older samples.
perf record:
Arnaldo Carvalho de Melo:
- Fix collection of build-ids when using setns() to get into namespaces,
which had been broken with the introduction of the extra thread to
react to PERF_RECORD_BPF_EVENT, i.e. to collect extra info for BPF
programs. We need to unshare(CLONE_FS) in that thread so that the
main one can do the setns(CLONE_NEWNS) when collectingthe build-ids.
Without that symbol resolution gets more difficult and potentially
misresolves symbols.
core:
Igor Lubashev:
- Further alignment in permission checking via capabilities to how the
kernel checks what tooling tries to do.
PowerPC:
Naveen N. Rao:
- Sync powerpc syscall.tbl, so that 'perf trace' gets the definitions
for recent syscalls.
libperf:
Jiri Olsa:
- Move the rest of the PERF_RECORD_ metadata struct definitions so that
we can use 'union perf_event'.
libtraceevent:
Steven Rostedt (VMware):
- Do not free tep->cmdlines in add_new_comm() on failure.
- Remove unneeded qsort and uses memmove instead

Test results:
The first ones are container based builds of tools/perf with and without libelf
support. Where clang is available, it is also used to build perf with/without
libelf, and building with LIBCLANGLLVM=1 (built-in clang) with gcc and clang
when clang and its devel libraries are installed.
The objtool and samples/bpf/ builds are disabled now that I'm switching from
using the sources in a local volume to fetching them from a http server to
build it inside the container, to make it easier to build in a container cluster.
Those will come back later.
Several are cross builds, the ones with -x-ARCH and the android one, and those
may not have all the features built, due to lack of multi-arch devel packages,
available and being used so far on just a few, like
debian:experimental-x-{arm64,mipsel}.
The 'perf test' one will perform a variety of tests exercising
tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf commands
with a variety of command line event specifications to then intercept the
sys_perf_event syscall to check that the perf_event_attr fields are set up as
expected, among a variety of other unit tests.
Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/
with a variety of feature sets, exercising the build with an incomplete set of
features as well as with a complete one. It is planned to have it run on each
of the containers mentioned above, using some container orchestration
infrastructure. Get in contact if interested in helping having this in place.
Clearlinux is failing when building with libpython, but that is not a perf
regression, will try to remove one compiler warning that is causing the problem
when building some of the glue code files in the python files, outside perf.

Test results:
The first ones are container based builds of tools/perf with and without libelf
support. Where clang is available, it is also used to build perf with/without
libelf, and building with LIBCLANGLLVM=1 (built-in clang) with gcc and clang
when clang and its devel libraries are installed.
The objtool and samples/bpf/ builds are disabled now that I'm switching from
using the sources in a local volume to fetching them from a http server to
build it inside the container, to make it easier to build in a container cluster.
Those will come back later.
Several are cross builds, the ones with -x-ARCH and the android one, and those
may not have all the features built, due to lack of multi-arch devel packages,
available and being used so far on just a few, like
debian:experimental-x-{arm64,mipsel}.
The 'perf test' one will perform a variety of tests exercising
tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf commands
with a variety of command line event specifications to then intercept the
sys_perf_event syscall to check that the perf_event_attr fields are set up as
expected, among a variety of other unit tests.
Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/
with a variety of feature sets, exercising the build with an incomplete set of
features as well as with a complete one. It is planned to have it run on each
of the containers mentioned above, using some container orchestration
infrastructure. Get in contact if interested in helping having this in place.
Clearlinux is failing when building with libpython, but that is not a perf
regression, will try to remove one compiler warning that is causing the problem
when building some of the glue code files in the python files, outside perf.

libperf: Fix alignment trap with xyarray contents in 'perf stat' (2019-08-22 17:16:57 -0300)
----------------------------------------------------------------
perf/core improvements and fixes:
perf c2c:
Ravi Bangoria:
- Fix report with offline cpus.
libperf:
Gerald BAEZA:
- Fix alignment trap with xyarray contents in 'perf stat', noticed on ARMv7.
Jiri Olsa:
- Move some more cpu_map and thread_map methods from tools/perf/util/ to libperf.
headers:
Arnaldo Carvalho de Melo:
- Do some house cleaning on the headers, removing needless includes in some places,
providing forward declarations when those are the only thing needed, and fixing
up the fallout from that for cases where we were using stuff and not adding the
necessary headers. Should speed up the build and avoid needless rebuilds when
something unrelated gets touched.

Test results:
The first ones are container based builds of tools/perf with and without libelf
support. Where clang is available, it is also used to build perf with/without
libelf, and building with LIBCLANGLLVM=1 (built-in clang) with gcc and clang
when clang and its devel libraries are installed.
The objtool and samples/bpf/ builds are disabled now that I'm switching from
using the sources in a local volume to fetching them from a http server to
build it inside the container, to make it easier to build in a container cluster.
Those will come back later.
Several are cross builds, the ones with -x-ARCH and the android one, and those
may not have all the features built, due to lack of multi-arch devel packages,
available and being used so far on just a few, like
debian:experimental-x-{arm64,mipsel}.
The 'perf test' one will perform a variety of tests exercising
tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf commands
with a variety of command line event specifications to then intercept the
sys_perf_event syscall to check that the perf_event_attr fields are set up as
expected, among a variety of other unit tests.
Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/
with a variety of feature sets, exercising the build with an incomplete set of
features as well as with a complete one. It is planned to have it run on each
of the containers mentioned above, using some container orchestration
infrastructure. Get in contact if interested in helping having this in place.
Clearlinux is failing when building with libpython, but that is not a perf
regression, will try to remove one compiler warning that is causing the problem
when building some of the glue code files in the python files, outside perf.

libperf: Fix arch include paths (2019-08-20 12:29:36 -0300)
----------------------------------------------------------------
perf/core improvements and fixes:
callchains:
Alexey Budankov:
- Allow collecting LBR together with DWARF callchains, for workloads
where the userspace stack size collected is not big enough for
pure DWARF based unwinding.
- Dump the LBR call stack in 'perf report -D'.
perf top:
Arnaldo Carvalho de Melo:
- Show visual cue at start to state that the minimal set of samples
are being collected prior to sorting/bucketizing/displaying.
CoreSight (ARM hardware tracing):
Leo Yan:
- Support sample flags 'insn' and 'insnlen'.
core:
Adrian Hunter:
- Add comment for 'idx' member in 'struct perf_sample_id.
tools headers:
Arnaldo Carvalho de Melo:
- Synchronize linux/bits.h, which required grabbing a copy of the kernel
const.h headers and some changes in the ordering of header directories.
- Sync x86's asm/cpufeatures.h with the with the kernel, no change in
any of the tools.
libperf:
Jiri Olsa:
- Fix arch include paths.
libtraceevent:
Steven Rostedt (VMware):
- Fix "robust" test of do_generate_dynamic_list_file.
Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>

Test results:
The first ones are container based builds of tools/perf with and without libelf
support. Where clang is available, it is also used to build perf with/without
libelf, and building with LIBCLANGLLVM=1 (built-in clang) with gcc and clang
when clang and its devel libraries are installed.
The objtool and samples/bpf/ builds are disabled now that I'm switching from
using the sources in a local volume to fetching them from a http server to
build it inside the container, to make it easier to build in a container cluster.
Those will come back later.
Several are cross builds, the ones with -x-ARCH and the android one, and those
may not have all the features built, due to lack of multi-arch devel packages,
available and being used so far on just a few, like
debian:experimental-x-{arm64,mipsel}.
The 'perf test' one will perform a variety of tests exercising
tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf commands
with a variety of command line event specifications to then intercept the
sys_perf_event syscall to check that the perf_event_attr fields are set up as
expected, among a variety of other unit tests.
Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/
with a variety of feature sets, exercising the build with an incomplete set of
features as well as with a complete one. It is planned to have it run on each

perf unwind: Remove unnecessary test (2019-08-16 12:30:14 -0300)
----------------------------------------------------------------
perf/core improvements and fixes:
report/script/trace/top:
Arnaldo Carvalho de Melo:
- Allow specifying marker events demarcating when to consider the other events,
i.e. one now can state something like:
# perf probe kernel_function
# perf record -e cycles,probe:kernel_function
And then, in 'perf script' or 'perf report' say:
# perf report --switch-on=probe:kernel_function
And then the cycles event samples will be considered only after we
find the first probe:kernel_function event.
There is also --switch-off=event, to make it stop considering events
out of some window, say to avoid some winding down of a workload.
The same can be done with the "live mode" tools: 'perf top' and 'perf trace'.
There are examples in the cset comments showing how to use it with
SDT events in things like 'systemtap', that have those tracepoint-like
events for the start/end of passes, etc.
Another example involves selecting scheduler events + entry/exit of
a syscall, using the syscalls tracepoints, one can then see the
scheduler events that take place while that syscall is being processed.
In the future this should be possible in record/top/trace via eBPF
where the perf tools would hook into the marker events and enable events
put in place but not enabled when the on/off conditions are the desired
ones, reducing the amount of events sampled, but this userspace only
solution should be good enough for many scenarios.
perf vendor events intel:
Haiyan Song:
- Add Tremontx event file v1.02.
unwind:
John Keeping:
- Fix callchain unwinding when tid != pid, that was working only for the
thread group leader.

Test results:
The first ones are container based builds of tools/perf with and without libelf
support. Where clang is available, it is also used to build perf with/without
libelf, and building with LIBCLANGLLVM=1 (built-in clang) with gcc and clang
when clang and its devel libraries are installed.
The objtool and samples/bpf/ builds are disabled now that I'm switching from
using the sources in a local volume to fetching them from a http server to
build it inside the container, to make it easier to build in a container cluster.
Those will come back later.
Several are cross builds, the ones with -x-ARCH and the android one, and those
may not have all the features built, due to lack of multi-arch devel packages,
available and being used so far on just a few, like
debian:experimental-x-{arm64,mipsel}.
The 'perf test' one will perform a variety of tests exercising
tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf commands
with a variety of command line event specifications to then intercept the
sys_perf_event syscall to check that the perf_event_attr fields are set up as
expected, among a variety of other unit tests.
Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/
with a variety of feature sets, exercising the build with an incomplete set of
features as well as with a complete one. It is planned to have it run on each
of the containers mentioned above, using some container orchestration
infrastructure. Get in contact if interested in helping having this in place.
Clearlinux is failing when building with libpython, but that is not a perf
regression, will try to remove one compiler warning that is causing the problem
when building some of the glue code files in the python files, outside perf.

perf ui: No need to set ui_browser to 1 twice (2019-08-14 11:00:00 -0300)
----------------------------------------------------------------
perf/core improvements and fixes:
Intel PT:
Adrian Hunter:
- Add PEBS via Intel PT support, the kernel bits went via PeterZ.
perf record:
Alexander Shishkin:
- Add an option to take an AUX snapshot on exit.
Tan Xiaojun:
- Support aarch64 random socket_id assignment, just like was fixed for S/390.
tools:
Andy Shevchenko:
- Keep list of tools in alphabetical order on 'make -C tools help'.
perf session:
Arnaldo Carvalho de Melo:
- Avoid infinite loop when seeing invalid header.size, reported by
Vince Weaver using a perf.data fuzzer.
Documentation:
Vince Weaver:
- Clarify HEADER_SAMPLE_TOPOLOGY format in the perf.data spec.
perf config:
Arnaldo Carvalho de Melo:
- Honour $PERF_CONFIG env var to specify alternate .perfconfig.
perf test:
Arnaldo Carvalho de Melo:
- Disable ~/.perfconfig to get default output in 'perf trace' tests.
perf top:
Arnaldo Carvalho de Melo:
- Set display thread COMM to help with debugging.
- Collapse and resort evsels in a group, so that we have output
similar to 'perf report' when using event groups, i.e.
perf top -e '{cycles,instructions}'
Will have two columns, and the instructions one will work.
core:
Igor Lubashev:
- Detect if libcap development files are available so that we
can use capabilities to match the checks made by the kernel instead
of using plain (geteuid() == 0).
Intel:
Haiyan Song:
- Add Icelake V1.00 event file.
perf trace:
Leo Yan:
- Fix segmentation fault when access syscall info on arm64.

Test results:
The first ones are container based builds of tools/perf with and without libelf
support. Where clang is available, it is also used to build perf with/without
libelf, and building with LIBCLANGLLVM=1 (built-in clang) with gcc and clang
when clang and its devel libraries are installed.
The objtool and samples/bpf/ builds are disabled now that I'm switching from
using the sources in a local volume to fetching them from a http server to
build it inside the container, to make it easier to build in a container cluster.
Those will come back later.
Several are cross builds, the ones with -x-ARCH and the android one, and those
may not have all the features built, due to lack of multi-arch devel packages,
available and being used so far on just a few, like
debian:experimental-x-{arm64,mipsel}.
The 'perf test' one will perform a variety of tests exercising
tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf commands
with a variety of command line event specifications to then intercept the
sys_perf_event syscall to check that the perf_event_attr fields are set up as
expected, among a variety of other unit tests.
Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/
with a variety of feature sets, exercising the build with an incomplete set of
features as well as with a complete one. It is planned to have it run on each
of the containers mentioned above, using some container orchestration
infrastructure. Get in contact if interested in helping having this in place.
Clearlinux is failing when building with libpython, but that is not a perf
regression, will try to remove one compiler warning that is causing the problem
when building some of the glue code files in the python files, outside perf.

perf version: Fix segfault due to missing OPT_END() (2019-07-15 07:59:05 -0300)
----------------------------------------------------------------
perf/core improvements and fixes:
perf db-export:
Adrian Hunter:
- Improvements in how COMM details are exported to databases for
post processing and use in the sql-viewer.py UI.
- Export switch events to the database.
BPF:
Arnaldo Carvalho de Melo:
- Bump rlimit(MEMLOCK) for 'perf test bpf' and 'perf trace', just like
selftests/bpf/bpf_rlimit.h do, which makes errors due to exhaustion of
this limit, which are kinda cryptic (EPERM sometimes) less frequent.
perf version:
Ravi Bangoria:
- Fix segfault due to missing OPT_END(), noticed on PowerPC.
perf vendor events:
Thomas Richter:
- Add JSON files for IBM s/390 machine type 8561.
perf cs-etm (ARM):
YueHaibing:
- Fix two cases of error returns not bing done properly: Invalid ERR_PTR() use
and loss of propagation error codes.
Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
----------------------------------------------------------------

Test results:
The first ones are container based builds of tools/perf with and without libelf
support. Where clang is available, it is also used to build perf with/without
libelf, and building with LIBCLANGLLVM=1 (built-in clang) with gcc and clang
when clang and its devel libraries are installed.
The objtool and samples/bpf/ builds are disabled now that I'm switching from
using the sources in a local volume to fetching them from a http server to
build it inside the container, to make it easier to build in a container cluster.
Those will come back later.
Several are cross builds, the ones with -x-ARCH and the android one, and those
may not have all the features built, due to lack of multi-arch devel packages,
available and being used so far on just a few, like
debian:experimental-x-{arm64,mipsel}.
The 'perf test' one will perform a variety of tests exercising
tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf commands
with a variety of command line event specifications to then intercept the
sys_perf_event syscall to check that the perf_event_attr fields are set up as
expected, among a variety of other unit tests.
Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/
with a variety of feature sets, exercising the build with an incomplete set of
features as well as with a complete one. It is planned to have it run on each
of the containers mentioned above, using some container orchestration
infrastructure. Get in contact if interested in helping having this in place.
The 'perf test bpf' test is about rlimit(MEMLOCK), bump it a to 128K from the
default 64K and it'll work. Next pull req will have auto-adjustment for 'perf
test' and 'perf trace', where BPF programs creating maps are also failing.

perf intel-pt: Fix potential NULL pointer dereference found by the smatch tool (2019-07-09 10:13:28 -0300)
----------------------------------------------------------------
perf/core improvements and fixes:
Intel PT:
Adrian Hunter:
- Fix DROP VIEW power_events_view in the postgresql and sqlite export-db
python scripts.
perf script:
Song Liu:
- Assume native_arch for pipe mode, fixing a segfault.
perf inject:
Arnaldo Carvalho de Melo:
- The tool->read() call may pass a NULL evsel, handle it.
core:
Arnaldo Carvalho de Melo:
- Move zalloc/zfree.c to tools/lib, further eroding tools/perf/util.[ch]
- Use zfree() where applicable instead of open coded equivalent.
- Add stdlib.h and some other headers to places where its needed and were
getting via util.h, that doesn't need that anymore.
- Use list_del_init() more thoroughly.
Miscellaneous:
Leo Yan:
- Fix use after free and potential NULL pointer derefs detected by the
smatch tool in various places.
Luke Mujica:
- Remove a couple unused variables in the parse-events code.
Numfor Mbiziwo-Tiapo:
- Initialize variable to suppress memory sanitizer warning in the
mmap-thread-lookup 'perf test' entry.

perf inject: The tool->read() call may pass a NULL evsel, handle it
perf evsel: perf_evsel__name(NULL) is valid, no need to check evsel
perf tools: Add missing headers, mostly stdlib.h
perf namespaces: Move the conditional setns() prototype to namespaces.h
perf tools: Move get_current_dir_name() cond prototype out of util.h
tools lib: Adopt zalloc()/zfree() from tools/perf
perf tools: Use zfree() where applicable
perf tools: Use list_del_init() more thorougly

Test results:
The first ones are container based builds of tools/perf with and without libelf
support. Where clang is available, it is also used to build perf with/without
libelf, and building with LIBCLANGLLVM=1 (built-in clang) with gcc and clang
when clang and its devel libraries are installed.
The objtool and samples/bpf/ builds are disabled now that I'm switching from
using the sources in a local volume to fetching them from a http server to
build it inside the container, to make it easier to build in a container cluster.
Those will come back later.
Several are cross builds, the ones with -x-ARCH and the android one, and those
may not have all the features built, due to lack of multi-arch devel packages,
available and being used so far on just a few, like
debian:experimental-x-{arm64,mipsel}.
The 'perf test' one will perform a variety of tests exercising
tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf commands
with a variety of command line event specifications to then intercept the
sys_perf_event syscall to check that the perf_event_attr fields are set up as
expected, among a variety of other unit tests.
Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/
with a variety of feature sets, exercising the build with an incomplete set of
features as well as with a complete one. It is planned to have it run on each
of the containers mentioned above, using some container orchestration
infrastructure. Get in contact if interested in helping having this in place.
The 'perf test bpf' test is about rlimit(MEMLOCK), bump it a to 128K from the
default 64K and it'll work. Next pull req will have auto-adjustment for 'perf
test' and 'perf trace', where BPF programs creating maps are also failing.

Test results:
The first ones are container based builds of tools/perf with and without libelf
support. Where clang is available, it is also used to build perf with/without
libelf, and building with LIBCLANGLLVM=1 (built-in clang) with gcc and clang
when clang and its devel libraries are installed.
The objtool and samples/bpf/ builds are disabled now that I'm switching from
using the sources in a local volume to fetching them from a http server to
build it inside the container, to make it easier to build in a container cluster.
Those will come back later.
Several are cross builds, the ones with -x-ARCH and the android one, and those
may not have all the features built, due to lack of multi-arch devel packages,
available and being used so far on just a few, like
debian:experimental-x-{arm64,mipsel}.
The 'perf test' one will perform a variety of tests exercising
tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf commands
with a variety of command line event specifications to then intercept the
sys_perf_event syscall to check that the perf_event_attr fields are set up as
expected, among a variety of other unit tests.
Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/
with a variety of feature sets, exercising the build with an incomplete set of
features as well as with a complete one. It is planned to have it run on each
of the containers mentioned above, using some container orchestration
infrastructure. Get in contact if interested in helping having this in place.
Investigating the failure for ubuntu:18.04-x-arm, doesn't look like something
introduced by this patchkit.
ubuntu:18.04-x-arm failure not yet resolved, doesn't seem related to
this patchkit nor the previous one.

perf jevents: Use nonlocal include statements in pmu-events.c (2019-07-01 22:50:42 -0300)
----------------------------------------------------------------
perf/core improvements and fixes:
perf annotate:
Mao Han:
- Add support for the csky processor architecture.
perf stat:
Andi Kleen:
- Fix metrics with --no-merge.
- Don't merge events in the same PMU.
- Fix group lookup for metric group.
Intel PT:
Adrian Hunter:
- Improve CBR (Core to Bus Ratio) packets support.
- Fix thread stack return from kernel for kernel only case.
- Export power and ptwrite events to sqlite and postgresql.
core libraries:
Arnaldo Carvalho de Melo:
- Find routines in tools/perf/util/ that have implementations in the kernel
libraries (lib/*.c), such as strreplace(), strim(), skip_spaces() and reuse
them after making a copy into tools/lib and tools/include/.
This continues the effort of having tools/ code looking as much as possible
like kernel source code, to help encourage people to work on both the kernel
and in tools hosted in the kernel sources.
That in turn will help moving stuff that uses those routines to
tools/lib/perf/ where they will be made available for use in other tools.
In the process ditch old cruft, remove unused variables and add missing
include directives for headers providing things used in places that were
building by sheer luck.
Kyle Meyer:
- Bump MAX_NR_CPUS and MAX_CACHES to get these tools to work on more machines.

Test results:
The first ones are container based builds of tools/perf with and without libelf
support. Where clang is available, it is also used to build perf with/without
libelf, and building with LIBCLANGLLVM=1 (built-in clang) with gcc and clang
when clang and its devel libraries are installed.
The objtool and samples/bpf/ builds are disabled now that I'm switching from
using the sources in a local volume to fetching them from a http server to
build it inside the container, to make it easier to build in a container cluster.
Those will come back later.
Several are cross builds, the ones with -x-ARCH and the android one, and those
may not have all the features built, due to lack of multi-arch devel packages,
available and being used so far on just a few, like
debian:experimental-x-{arm64,mipsel}.
The 'perf test' one will perform a variety of tests exercising
tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf commands
with a variety of command line event specifications to then intercept the
sys_perf_event syscall to check that the perf_event_attr fields are set up as
expected, among a variety of other unit tests.
Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/
with a variety of feature sets, exercising the build with an incomplete set of
features as well as with a complete one. It is planned to have it run on each
of the containers mentioned above, using some container orchestration
infrastructure. Get in contact if interested in helping having this in place.
Investigating the failure for ubuntu:18.04-x-arm, doesn't look like something
introduced by this patchkit.

tools build: Fix the zstd test in the test-all.c common case feature test (2019-06-18 18:44:24 -0300)
----------------------------------------------------------------
perf/core improvements and fixes:
perf trace:
Arnaldo Carvalho de Melo:
- Fix exclusion of not available syscall names from selector list.
- Fixup pointer arithmetic when consuming augmented syscall args.
Intel PT:
Adrian Hunter:
- Add support for decoding PEBS via PT packets. See:
https://software.intel.com/en-us/articles/intel-sdm
May 2019 version: Vol. 3B 18.5.5.2 PEBS output to Intel® Processor Trace
for more details about it.
ARM64:
John Garry:
- Fix uncore PMU alias list for ARM64
Raphael Gault:
- Compile tests unconditionally.
cs-etm:
Mathieu Poirier:
- Optimize option setup for CPU-wide sessions.
build:
Florian Fainelli:
- Don't hardcode host include path for libslang, fixing up building with it
in cross build environments.
Arnaldo Carvalho de Melo:
- Check if gettid() is available before providing helper, fixing the build
when using the latest glibc version, where a helper for gettid() is finally
present.
- Fix building with libslang in systems where it is located in slang/slang.h.
- Fix fast path test for zstd library.

Test results:
The first ones are container based builds of tools/perf with and without libelf
support. Where clang is available, it is also used to build perf with/without
libelf, and building with LIBCLANGLLVM=1 (built-in clang) with gcc and clang
when clang and its devel libraries are installed.
The objtool and samples/bpf/ builds are disabled now that I'm switching from
using the sources in a local volume to fetching them from a http server to
build it inside the container, to make it easier to build in a container cluster.
Those will come back later.
Several are cross builds, the ones with -x-ARCH and the android one, and those
may not have all the features built, due to lack of multi-arch devel packages,
available and being used so far on just a few, like
debian:experimental-x-{arm64,mipsel}.
The 'perf test' one will perform a variety of tests exercising
tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf commands
with a variety of command line event specifications to then intercept the
sys_perf_event syscall to check that the perf_event_attr fields are set up as
expected, among a variety of other unit tests.
Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/
with a variety of feature sets, exercising the build with an incomplete set of
features as well as with a complete one. It is planned to have it run on each
of the containers mentioned above, using some container orchestration
infrastructure. Get in contact if interested in helping having this in place.

perf trace: Skip unknown syscalls when expanding strace like syscall groups (2019-06-10 17:50:04 -0300)
----------------------------------------------------------------
perf/core improvements and fixes:
perf record:
Alexey Budankov:
- Allow mixing --user-regs with --call-graph=dwarf, making sure that
the minimal set of registers for DWARF unwinding is present in the
set of user registers requested to be present in each sample, while
warning the user that this may make callchains unreliable if more
that the minimal set of registers is needed to unwind.
yuzhoujian:
- Add support to collect callchains from kernel or user space only,
IOW allow setting the perf_event_attr.exclude_callchain_{kernel,user}
bits from the command line.
perf trace:
Arnaldo Carvalho de Melo:
- Remove x86_64 specific syscall numbers from the augmented_raw_syscalls
BPF in-kernel collector of augmented raw_syscalls:sys_{enter,exit}
payloads, use instead the syscall numbers obtainer either by the
arch specific syscalltbl generators or from audit-libs.
- Allow 'perf trace' to ask for the number of bytes to collect for
string arguments, for now ask for PATH_MAX, i.e. the whole
pathnames, which ends up being just a way to speficy which syscall
args are pathnames and thus should be read using bpf_probe_read_str().
- Skip unknown syscalls when expanding strace like syscall groups.
This helps using the 'string' group of syscalls to work in arm64,
where some of the syscalls present in x86_64 that deal with
strings, for instance 'access', are deprecated and this should not
be asked for tracing.
Leo Yan:
- Exit when failing to build eBPF program.
perf config:
Arnaldo Carvalho de Melo:
- Bail out when a handler returns failure for a key-value pair. This
helps with cases where processing a key-value pair is not just a
matter of setting some tool specific knob, involving, for instance
building a BPF program to then attach to the list of events 'perf
trace' will use, e.g. augmented_raw_syscalls.c.
perf.data:
Kan Liang:
- Read and store die ID information available in new Intel processors
in CPUID.1F in the CPU topology written in the perf.data header.
perf stat:
Kan Liang:
- Support per-die aggregation.
Documentation:
Arnaldo Carvalho de Melo:
- Update perf.data documentation about the CPU_TOPOLOGY, MEM_TOPOLOGY,
CLOCKID and DIR_FORMAT headers.
Song Liu:
- Add description of headers HEADER_BPF_PROG_INFO and HEADER_BPF_BTF.
Leo Yan:
- Update default value for llvm.clang-bpf-cmd-template in 'man perf-config'.
JVMTI:
Jiri Olsa:
- Address gcc string overflow warning for strncpy()
core:
- Remove superfluous nthreads system_wide setup in perf_evsel__alloc_fd().
Intel PT:
Adrian Hunter:
- Add support for samples to contain IPC ratio, collecting cycles
information from CYC packets, showing the IPC info periodically, because
Intel PT does not update the cycle count on every branch or instruction,
the incremental values will often be zero. When there are values, they
will be the number of instructions and number of cycles since the last
update, and thus represent the average IPC since the last IPC value.
E.g.:
# perf record --cpu 1 -m200000 -a -e intel_pt/cyc/u sleep 0.0001
rounding mmap pages size to 1024M (262144 pages)
[ perf record: Woken up 0 times to write data ]
[ perf record: Captured and wrote 2.208 MB perf.data ]
# perf script --insn-trace --xed -F+ipc,-dso,-cpu,-tid
#
<SNIP + add line numbering to make sense of IPC counts e.g.: (18/3)>

Test results:
The first ones are container based builds of tools/perf with and without libelf
support. Where clang is available, it is also used to build perf with/without
libelf, and building with LIBCLANGLLVM=1 (built-in clang) with gcc and clang
when clang and its devel libraries are installed.
The objtool and samples/bpf/ builds are disabled now that I'm switching from
using the sources in a local volume to fetching them from a http server to
build it inside the container, to make it easier to build in a container cluster.
Those will come back later.
Several are cross builds, the ones with -x-ARCH and the android one, and those
may not have all the features built, due to lack of multi-arch devel packages,
available and being used so far on just a few, like
debian:experimental-x-{arm64,mipsel}.
The 'perf test' one will perform a variety of tests exercising
tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf commands
with a variety of command line event specifications to then intercept the
sys_perf_event syscall to check that the perf_event_attr fields are set up as
expected, among a variety of other unit tests.
Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/
with a variety of feature sets, exercising the build with an incomplete set of
features as well as with a complete one. It is planned to have it run on each
of the containers mentioned above, using some container orchestration
infrastructure. Get in contact if interested in helping having this in place.

Hi Ingo,
Please consider pulling, I pulled tip/perf/urgent into
tip/pref/core, IIRC was just a fast forward at that point, yeap, just
did it again and it still is:
$ git checkout -b t tip/perf/core
Branch 't' set up to track remote branch 'perf/core' from 'tip'.
Switched to a new branch 't'
$ git merge tip/perf/urgent
Updating d15d356887e7..c7a286577d75
Fast-forward
<SNIP>
IIRC Jiri needs this for a pile of patches he submitted and
that I'll process next,
Best regards,
- Arnaldo

perf stat: Support 'percore' event qualifier (2019-05-16 14:17:24 -0300)
----------------------------------------------------------------
perf/core improvements and fixes:
perf.data:
Alexey Budankov:
- Streaming compression of perf ring buffer into PERF_RECORD_COMPRESSED
user space records, resulting in ~3-5x perf.data file size reduction
on variety of tested workloads what saves storage space on larger
server systems where perf.data size can easily reach several tens or
even hundreds of GiBs, especially when profiling with DWARF-based
stacks and tracing of context switches.
perf record:
Arnaldo Carvalho de Melo
- Improve -user-regs/intr-regs suggestions to overcome errors.
perf annotate:
Jin Yao:
- Remove hist__account_cycles() from callback, speeding up branch processing
(perf record -b).
perf stat:
- Add a 'percore' event qualifier, e.g.: -e cpu/event=0,umask=0x3,percore=1/,
that sums up the event counts for both hardware threads in a core.
We can already do this with --per-core, but it's often useful to do
this together with other metrics that are collected per hardware thread.
I.e. now its possible to do this per-event, and have it mixed with other
events not aggregated by core.
core libraries:
Donald Yandt:
- Check for errors when doing fgets(/proc/version).
Jiri Olsa:
- Speed up report for perf compiled with linbunwind.
tools headers:
Arnaldo Carvalho de Melo
- Update memcpy_64.S, x86's kvm.h and pt_regs.h.
arm64:
Florian Fainelli:
- Map Brahma-B53 CPUID to cortex-a53 events.
- Add Cortex-A57 and Cortex-A72 events.
csky:
Mao Han:
- Add DWARF register mappings for libdw, allowing --call-graph=dwarf to work
on the C-SKY arch.
x86:
Andi Kleen/Kan Liang:
- Add support for recording and printing XMM registers, available, for
instance, on Icelake.
Kan Liang:
- Add uncore_upi (Intel's "Ultra Path Interconnect" events) JSON support.
UPI replaced the Intel QuickPath Interconnect (QPI) in Xeon Skylake-SP.
Intel PT:
Adrian Hunter
. Fix instructions sampling rate.
. Timestamp fixes.
. Improve exported-sql-viewer GUI, allowing, for instance, to copy'n'paste
the trees, useful for e-mailing.
Documentation:
Thomas Richter:
- Add description for 'perf --debug stderr=1', which redirects stderr to stdout.
libtraceevent:
Tzvetomir Stoyanov:
- Add man pages for the various APIs.

Test results:
The first ones are container based builds of tools/perf with and without libelf
support. Where clang is available, it is also used to build perf with/without
libelf, and building with LIBCLANGLLVM=1 (built-in clang) with gcc and clang
when clang and its devel libraries are installed.
The objtool and samples/bpf/ builds are disabled now that I'm switching from
using the sources in a local volume to fetching them from a http server to
build it inside the container, to make it easier to build in a container cluster.
Those will come back later.
Several are cross builds, the ones with -x-ARCH and the android one, and those
may not have all the features built, due to lack of multi-arch devel packages,
available and being used so far on just a few, like
debian:experimental-x-{arm64,mipsel}.
The 'perf test' one will perform a variety of tests exercising
tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf commands
with a variety of command line event specifications to then intercept the
sys_perf_event syscall to check that the perf_event_attr fields are set up as
expected, among a variety of other unit tests.
Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/
with a variety of feature sets, exercising the build with an incomplete set of
features as well as with a complete one. It is planned to have it run on each
of the containers mentioned above, using some container orchestration
infrastructure. Get in contact if interested in helping having this in place.

The getname_flags related tests failing at the end (tests 65, 66 and 67) are
being investigated, getname_flags() seems to have become just a tail call from
getname(), something in this are changed and we're not anymore being able to
add a probe at a suitable place to collect the just copied from userspace
pathname.

Test results:
The first ones are container based builds of tools/perf with and without libelf
support. Where clang is available, it is also used to build perf with/without
libelf, and building with LIBCLANGLLVM=1 (built-in clang) with gcc and clang
when clang and its devel libraries are installed.
The objtool and samples/bpf/ builds are disabled now that I'm switching from
using the sources in a local volume to fetching them from a http server to
build it inside the container, to make it easier to build in a container cluster.
Those will come back later.
Several are cross builds, the ones with -x-ARCH and the android one, and those
may not have all the features built, due to lack of multi-arch devel packages,
available and being used so far on just a few, like
debian:experimental-x-{arm64,mipsel}.
The 'perf test' one will perform a variety of tests exercising
tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf commands
with a variety of command line event specifications to then intercept the
sys_perf_event syscall to check that the perf_event_attr fields are set up as
expected, among a variety of other unit tests.
Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/
with a variety of feature sets, exercising the build with an incomplete set of
features as well as with a complete one. It is planned to have it run on each
of the containers mentioned above, using some container orchestration
infrastructure. Get in contact if interested in helping having this in place.
